The Sacalho project, by Guilherme Giantini, a master’s student in Industrial and Product Design, gives garlic peels a purpose by using them as the basis for a bio-textile. The idea won the international DNA Paris Design Awards 2024, in the Product Design / Ecodesign – Students category.
“Sacalho came about to promote the creation of alternative, bio-based materials to those commonly used for profit on the market. It all started to take shape from the use of various types of food waste: coffee grounds, wood ash, peanut shells and garlic husks,” shares the University of Porto.
The project had scientific mentoring from Lígia Lopes, director of the master’s programme in Industrial and Product Design at the Faculty of Fine Arts of the University of Porto, and manufacturing support from Jorge Lino Alves, a lecturer in the materials and technological processes section of the mechanical engineering department of the Faculty of Engineering of the University of Porto.
